Port that exhaust manifold while its off.. I managed to twist my main gas line when removing.. looks like you have a replacement bulk head? I resorted to getting an an-8 fitting welded on because I tried bolt on bulk heads and they would leak.
Yeah its a replacement bulkhead. Those brass nuts are the weakest pieces of crap. 2 line wrenches and alot of silicone lube and I still smoothed the nut.
Hopefully this bulkhead holds I have a nylon washer on fuel side and a crush washer on the top which I coated with gasket maker. It's the same as the RTM repair kit except I didn't want to change to AN fittings yet. If I switch to AN I will likely replace the hardlines all the way to the engine bay.
Sounds good, I went through 6 revisions or more trying to use bolt on an bulkheads and I swear I don't know how it managed to leak. I added nylon washers to both sides, pipe dope quite a few tricks and wasn't happy with it. Even when I got it to stop leaking I could smell gas through it and not going to accept that. Got it welded so I could have piece of mind over some time it won't develop another leak.
